  1. *: Indicates a value that is significantly different from that of stage 0 in the same column, with p < 0.05
  2. **: Indicates a value that is significantly different from that of stage 0 in the same column, with p < 0.01
  3. aIndicates a value that is significantly different from neutral rotation in the same row
